r WATER-HEATER.

To all whom it may concern:

Be it known that I, JOHN THEODORE MIGOHELBRINK, a citizen of the United States residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Water-Heaters, of which the following is a full, clear and exact description.

This invention relates to a water heater and more particularly to a unit of a water heater which may be duplicated to form a heater of desired capacity.

Generally speaking, the invention comprises the elements and combinations thereof set forth in the accompanying claims.

Reference should be had to the accompanying drawing forming a part of this specification, in which Figure 1 is an elevation of a water heater embodying my invention; Fig. 2 is a top plan view of an element or unit of my heater construction; Fig. 3 is a. section upon line 33 of Fig. 2; Fig. 4 is a section upon a line at right angles to the showing in Fig. 3; Fig. 5 is a front elevation of such an element as shown in Fig. 2.

A hot water heating device embodying my invention is represented in Fig. 1, wherein there are a number of superimposed units which are generally represented at 1. Each unit has an inlet portion 2 and an outlet portion 3. the outlet portion of each unit being connected with the inlet portion of a superimposed unit. The outlet from the last or topmost section being connected with the pipe 4: by which water is conducted from the heater to the piping system which is to be supplied. The lowermost unit has its inlet connected with a pipe 5 by which water is fed to the elements of the heater.

The units 1 are inclosed in a. casing 6 which at the lower part and beneath the lowermost unit, supports a gas burner 7 which is representative of any means for heating the units 1. The casing 6 may be connected with a flue, as indicated at 8. Each unit comprises two oppositely disposed chambered portions 9 and 10 which serve one as a water inlet and the other as a water outlet. These portions 9 and 10 are spaced apart so that the heated products of combustion from the burner may freely circulate around them.

The chambered portions 9 and 10 are connected by a plurality of water conducting Specification of Letters Patent.

portions, two of which are indicated at 11 and 12. The portions 11 and 12 may bedescribed as arc-shaped and are connected to the chambered portions 9 and; 10 by necks which eXtend inwardly from the ends of the arc-shaped portions 11 and 12. The portion 11 is connected with chambered portions 9 and 10 by necks 11 and 11 While portion 12 is connected by necks 12 and 12 Necks 11 and 12 and necks 11 and 12 extend substantially parallel and are spaced apart to permit the passage of heated gases. Between the arc-shaped portions 11, 12 and the inwardly extending necks-and their corresponding necks 11 11 and 12, 12 respectively. are arc-shaped slots 13 and 14 which permit passage of heated gases. 7 It will thus be seen that the heated gases from the burner may pass upwardly and around all portions of thewater conducting portions of theunits. Each of the arc-shaped portions of the units is slightly upwardly inclined which will promote the natural flow of the water through the unit. The water enters the unit through the lowermost chambered portion which as shown is chambered portion 10 and divides part flowing through neck 11, arc-shaped portion 11 and neck 11 and part flowing through neck 12, areshaped portion 12 and neck 12*. The water traveling byboth paths described unites in chambered portion 9 and thence passes to the next unit of the heater. Assuming that the chambered portion 10 is the inlet. it will be seen that the neck 12 leads from the inlet 10 in a direction opposite the direction by which water is conducted through neck 11", and so whatever the number of water conducting portions between the inlet and outlet. each will conduct water from the inlet in a diiferent direction. This water entering at the inlet is divided into a plurality of streams that spread away from inlet and so the portions conducting these streams are brought into contact with all of the hot gases arising from the burner.

While I have shown two water conducting portions connecting the inlet and outlet for each section, I do not limit myself in this respect.

It is desired to call special attention to the fact that the water as it flows from inlet to outletof a section follows paths Which are distinct and separated by spaces whereby the water is contlnually heated. as it moves through a section. The inlet and outlet chambers are separated by a space through which heated gases may pass and so the incoming water has no cooling effect upon the outgoing water such as is common in those constructions which employ a partition between the inlet and outlet chambers.

Various details of construction may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim is z- 1. A water heating unit comprising upper and lower chambered portions said portions being spaced apart so that heated gases may pass betweenthem. a plurality of hollow arms extending from the lower chambered. portion a phiralit. of hollow arms extend ing from the upper chambered portion, a hollow body joining each lower arm with an upper arm each hollow bodv being spaced from the said chambered portions to form an opening.

2. A water heating unit comprising upper and lower chambered portions, means connecting the lower and upper chambered portions said means comprising a neck extend ing outwardly from one chambered portion, a curved portion substantially concentric with the center point of the chambered por tions, and a neck leading inwardly to the other chambered portion the curved portion being spaced from the said chambered portions to form an opening.

3. A water heating unit comprising upper and lower chambered portions, a plurality of means connecting the lower and upper chambered portions, each of said means comprising a neck extending outwardly from one of the chambered portions, a curved portion substantially concentric with the center point of the chambered portions, and a neck leading inwardly to the other chambered portion the curved portion being spaced from the said chambered portions to form an. opening.

i. A water heating unit comprising upper and lower chambered portions which are spaced apart so that heated gases mav pass between them, a hollow curved member spaced from the chambered portions, hollow arms extending in different directions from said chambered portions said arms connecting with opposite ends of the curved mem her.

in testimonr whereof, I hereunto my signature in the presence of two witnesses.
